AT&T announced today that its LTE network will expand to four additional markets on November 6. Those markets include Athens, Baltimore, Boston, and Washington, D.C. These deployments join AT&T's initial rollout last month (Atlanta, Chicago, Dallas, Houston, and San Antonio).

To kickoff the expansion of its LTE network, AT&T will also launch its first LTE smartphones on November 6. These include the HTC Vivid and the Samsung Galaxy S II Skyrocket.

The HTC Vivid will be priced at $199 with a two-year contract, while the Samsung Galaxy S II Skyrocket will be priced at $249 with a two-year contract.

“We’ve far exceeded our commitment to offer 12 new Android devices this year –now including our first 4G LTE smartphones, said AT&T Mobility and Consumer Markets CMO David Christopher. “We’re delivering an incredible amount of innovation to our customers, which is a huge reason why more than half our post-paid subscribers are using a smartphone.”
